Allelochemical effects on net nitrate uptake and plasma membrane H+-ATPase activity in maize seedlings

open access: yesBiologia Plantarum, 2010
Seven-day-old maize seedlings grown in a nitrogen-free hydroponic culture were exposed for 48 h to 0, 100 and 300 μM trans-cinnamic, p-coumaric, ferulic, caffeic acids, umbelliferone and 200 μM KNO3.

Natural variation in HvAT10 underlies grain cell wall-esterified phenolic acid content in cultivated barley

open access: yesFrontiers in Plant Science, 2023
The phenolic acids, ferulic acid and p-coumaric acid, are components of plant cell walls in grasses, including many of our major food crops. They have important health-promoting properties in grain, and influence the digestibility of biomass for ...

Exogenously applied ferulic acid and p-coumaric acid differentially affect cucumber rhizosphere Trichoderma spp. community structure and abundance

open access: yesPlant, Soil and Environment, 2020
Continuous monocropping can cause the buildup of autotoxins (e.g., phenolic compounds) in the soil, which can alter soil microbial community and inhibit plant growth.

Merging Biocatalysis and Chemocatalysis in Flow: State‐of‐the‐Art and Future Directions for Sustainable Synthesis

open access: yesAngewandte Chemie, EarlyView.
This review highlights recent advances in integrating biocatalysis and chemocatalysis in continuous flow to create streamlined, sustainable processes. It examines chemo‐enzymatic cascades combining at least one enzymatic and one chemical step, discusses challenges such as enzyme immobilization, leaching, and reactor clogging, and presents solutions ...

Individual Phenolic Acids in Distillery Stillage Inhibit Its Biomethanization

open access: yesEnergies, 2022
Polyphenols that are abundant in various organic wastes can inhibit anaerobic degradation of these wastes. This study investigated the effect of the concentration of individual phenolic acids (p-OH benzoic, vanillic, ferulic, sinapic, syringic, and p ...

The phenolic acids of some species of the Oenothera L. genus

open access: yesActa Societatis Botanicorum Poloniae, 2014
The occurence and approximative quantitative proportions of the phenolic acids in four species of the Oenothera L. genus was determined by the method of TLC and HPLC. In all species of Oenothera L.
